Request InfoPromega Corp.Promega Corp. has launched the ROS-Glo H2O2, a nonhorseradish peroxidase (HRP)-dependent, plate-based bioluminescent assay designed to detect reactive oxygen species (ROS). It measures the activity of enzymes that generate or eliminate H2O2 and enables small-molecule screening, including low false hit rate, signal stability and compatibility with liquid handling. The homogeneous assay does not rely on a reaction catalyzed by HRP, which causes a high number of false hits. It also can be used to measure changes in the level of ROS by directly detecting H2O2 in cultured mammalian...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra July 2022 IssueFluorescence Filter SetKnight Optical LLC’s fluorescence filter set range suits the diverse needs of various fluorescence applications that demand high-quality components.
